Distinct parameter not documented

[gallardoalba]

The distinct parameter, used for generating the high frequency k-mers datasets required by winnowmap, is not documented at all I think.

• Mapping ONT or PacBio-hifi WGS reads

meryl count k=15 output merylDB ref.fa
meryl print greater-than distinct=0.9998 merylDB > repetitive_k15.txt
winnowmap -W repetitive_k15.txt -ax map-ont ref.fa ont.fq.gz > output.sam

Do you (or anyone) know what the distinct parameter means? More specifically what does
meryl print greater-than distinct=0.9998 merylDB
mean???
I believe that "meryl print greater-than 2" would mean to print out all kmers that are present in the reads at least twice.
But what does distinct=0.9998 mean? Some sort of fraction? Of what? A wild guess: print kmers that occur once in the reads (are distinct) but only if such kmers occur 0.9998 of all kmers in the reads.
